FIELD OF THE INVENTION

The present disclosure relates to solid forms of Compound I or a pharmaceutically acceptable salt and/or solvate thereof, pharmaceutical compositions comprising the crystalline form, and therapeutic uses thereof. In particular, the present disclosure relates to solid forms of Compound I or a pharmaceutically acceptable salt and/or solvate thereof, which are useful for treating various diseases, including cancers such as prostate cancer.

BACKGROUND OF THE INVENTION

Androgens mediate their effects through the androgen receptor (AR). Androgens play a role in a wide range of developmental and physiological responses and are involved in male sexual differentiation, maintenance of spermatogenesis, and male gonadotropin regulation (R. K. Ross, G. A. Coetzee, C. L. Pearce, J. K. Reichardt, P. Bretsky, L. N. Kolonel, B. E. Henderson, E. Lander, D. Altshuler & G. Daley, Eur Urol 35, 355-361 (1999); A. A. Thomson, Reproduction 121, 187-195 (2001); N. Tanji, K. Aoki & M. Yokoyama, Arch Androl 47, 1-7 (2001)). Several lines of evidence show that androgens are associated with the development of prostate carcinogenesis. Firstly, androgens induce prostatic carcinogenesis in rodent models (R. L. Noble, Cancer Res 37, 1929-1933 (1977); R. L. Noble, Oncology 34, 138-141 (1977)) and men receiving androgens in the form of anabolic steroids have a higher incidence of prostate cancer (J. T. Roberts & D. M. Essenhigh, Lancet 2, 742 (1986); J. A. Jackson, J. Waxman & A. M. Spiekerman, Arch Intern Med 149, 2365-2366 (1989); P. D. Guinan, W. Sadoughi, H. Alsheik, R. J. Ablin, D. Alrenga & I. M. Bush, Am J Surg 131, 599-600 (1976)). Secondly, prostate cancer does not develop if humans or dogs are castrated before puberty (J. D. Wilson & C. Roehrborn, J Clin Endocrinol Metab 84, 4324-4331 (1999); G. Wilding, Cancer Surv 14, 113-130 (1992)). Castration of adult males causes involution of the prostate and apoptosis of prostatic epithelium while eliciting no effect on other male external genitalia (E. M. Bruckheimer & N. Kyprianou, Cell Tissue Res 301, 153-162 (2000); J. T. Isaacs, Prostate 5, 545-557 (1984)). This dependency on androgens provides the underlying rationale for treating prostate cancer with chemical or surgical castration also known as androgen ablation therapy (ABT) or androgen deprivation therapy (ADT).

Androgen receptor (AR) is a transcription factor that plays dual roles in breast cancer cells: promoting or inhibiting proliferation depending on expression and activity of estrogen receptor-alpha. Expression of AR is detected in up to 90% of all breast cancers.

Androgens also play a role in female diseases such as polycystic ovary syndrome as well as cancers. One example is ovarian cancer where elevated levels of androgens are associated with an increased risk of developing ovarian cancer (K. J. Helzlsouer, A. J. Alberg, G. B. Gordon, C. Longcope, T. L. Bush, S. C. Hoffman & G. W. Comstock, JAMA 274, 1926-1930 (1995); R. J. Edmondson, J. M. Monaghan & B. R. Davies, Br J Cancer 86, 879-885 (2002)). The AR has been detected in a majority of ovarian cancers (H. A. Risch, J Natl Cancer Inst 90, 1774-1786 (1998); B. R. Rao & B. J. Slotman, Endocr Rev 12, 14-26 (1991); G. M. Clinton & W. Hua, Crit Rev Oncol Hematol 25, 1-9 (1997)), whereas estrogen receptor-alpha (ERa) and the progesterone receptor are detected in less than 50% of ovarian tumors.

The only effective treatment available for advanced prostate cancer is the withdrawal of androgens which are essential for the survival of prostate luminal cells. Androgen ablation therapy causes a temporary reduction in tumor burden concomitant with a decrease in serum prostate-specific antigen (PSA). Unfortunately, prostate cancer can eventually grow again in the absence of testicular androgens (castration-resistant disease) (Huber et al 1987 Scand J. Urol Nephrol. 104, 33-39). Castration-resistant prostate cancer that is still driven by AR is biochemically characterized before the onset of symptoms by a rising titre of serum PSA (Miller et al 1992 J. Urol. 147, 956-961). Once the disease becomes castration-resistant most patients succumb to their disease within two years.

The AR has distinct functional domains that include the carboxy-terminal ligand-binding domain (LBD), a DNA-binding domain (DBD) comprising two zinc finger motifs, and an N-terminus domain (NTD) that contains two transcriptional activation units (tau1 and tau5) within activation function-1 (AF-1). Binding of androgen (ligand) to the LBD of the AR results in its activation such that the receptor can effectively bind to its specific DNA consensus site, termed the androgen response element (ARE), on the promoter and enhancer regions of “normally” androgen regulated genes, such as PSA, to initiate transcription. The AR can be activated in the absence of androgen by stimulation of the cAMP-dependent protein kinase (PKA) pathway, with interleukin-6 (IL-6) and by various growth factors (Culig et al 1994 Cancer Res. 54, 5474-5478; Nazareth et al 1996 J. Biol. Chem. 271, 19900-19907; Sadar 1999 J. Biol. Chem. 274, 7777-7783; Ueda et al 2002 A J. Biol. Chem. 277, 7076-7085; and Ueda et al 2002 B J. Biol. Chem. 277, 38087-38094). The mechanism of ligand-independent transformation of the AR has been shown to involve: 1) increased nuclear AR protein suggesting nuclear translocation; 2) increased AR/ARE complex formation; and 3) the AR-NTD (Sadar 1999 J. Biol. Chem. 274, 7777-7783; Ueda et al 2002 A J. Biol. Chem. 277, 7076-7085; and Ueda et al 2002 B J. Biol. Chem. 277, 38087-38094). The AR can be activated in the absence of testicular androgens by alternative signal transduction pathways in castration-resistant disease, which is consistent with the finding that nuclear AR protein is present in secondary prostate cancer tumors (Kim et al 2002 Am. J. Pathol. 160, 219-226; and van der Kwast et al 1991 Inter. J. Cancer 48, 189-193).

Clinically available inhibitors of the AR include nonsteroidal antiandrogens such as bicalutamide (Casodex™), nilutamide, flutamide, and enzalutamide. There is also a class of steroidal antiandrogens, such as cyproterone acetate and spironolactone. Both steroidal and non-steroidal antiandrogens target the LBD of the AR and predominantly fail presumably due to poor affinity and mutations that lead to activation of the AR by these same antiandrogens (Taplin, M. E., Bubley, G. J., Kom Y. J., Small E. J., Uptonm M., Rajeshkumarm B., Balkm S. P., Cancer Res., 59, 2511-2515 (1999)), and constitutively active AR splice variants. Antiandrogens have no effect on the constitutively active AR splice variants that lack the ligand-binding domain (LBD) and are associated with castration-recurrent prostate cancer (Dehm S M, Schmidt L J, Heemers H V, Vessella R L, Tindall D J., Cancer Res 68, 5469-77, 2008; Guo Z, Yang X, Sun F, Jiang R, Linn D E, Chen H, Chen H, Kong X, Melamed J, Tepper C G, Kung H J, Brodie A M, Edwards J, Qiu Y., Cancer Res. 69, 2305-13, 2009; Hu et al 2009 Cancer Res. 69, 16-22; Sun et al 2010 J Clin Invest. 2010 120, 2715-30) and resistant to abiraterone and enzalutamide (Antonarakis et al., N Engl J Med. 2014, 371, 1028-38; Scher et al JAMA Oncol. 2016 doi: 10.1001). Conventional therapy has concentrated on androgen-dependent activation of the AR through its C-terminal domain.

Other relevant AR antagonists previously reported (see, WO 2010/000066, WO 2011/082487; WO 2011/082488; WO 2012/145330; WO 2015/031984; WO 2016/058080; and WO 2016/058082) that bind to full-length AR and/or truncated AR splice variants that are currently being developed include: AR degraders such as niclosamide (Liu C et al 2014), galeterone (Njar et al 2015; Yu Z at al 2014), and ARV-330/Androgen receptor PROTAC (Neklesa et al 2016 J. Clin Oncol 34 suppl 2S; abstr 267); AR DBD inhibitor VPC-14449 (Dalal K et al 2014 J Biol Chem. 289(38):26417-29; Li H et al 2014 J Med Chem. 57(15):6458-67); antiandrogens apalutamide (Clegg N J et al 2012), ODM-201 (Moilanen A M et al 2015), ODM-204 (Kallio et al J Clin Oncol 2016 vol. 34 no. 2_suppl 230), TAS3681 (Minamiguchi et al 2015 J Clin Oncol 33, suppl 7; abstr 266); and AR NTD inhibitors 3E10-AR441bsAb (Goicochea N L et al 2015), and sintokamide (Sadar et al 2008; Banuelos et al 2016).

The AR-NTD is also a target for drug development (e.g. WO 2000/001813; Myung et al. J. Clin. Invest 2013, 123, 2948), since the NTD contains Activation-Function-1 (AF-1) which is the essential region required for AR transcriptional activity (Jenster et al 1991. Mol Endocrinol. 5, 1396-404). The AR-NTD importantly plays a role in activation of the AR in the absence of androgens (Sadar, M. D. 1999 J. Biol. Chem. 274, 7777-7783; Sadar M D et al 1999 Endocr Relat Cancer. 6, 487-502; Ueda et al 2002 J. Biol. Chem. 277, 7076-7085; Ueda 2002 J. Biol. Chem. 277, 38087-38094; Blaszczyk et al 2004 Clin Cancer Res. 10, 1860-9; Dehm et al 2006 J Biol Chem. 28, 27882-93; Gregory et al 2004 J Biol Chem. 279, 7119-30). The AR-NTD is important in hormonal progression of prostate cancer as shown by application of decoy molecules (Quayle et al 2007, Proc Natl Acad Sci USA. 104, 1331-1336).

While the crystal structure has been resolved for the AR C-terminus LBD, this has not been the case for the NTD due to its high flexibility and intrinsic disorder in solution (Reid et al 2002 J. Biol. Chem. 277, 20079-20086) thereby hampering virtual docking drug discovery approaches. Compounds that modulate AR, potentially through interaction with NTD domain, include the bisphenol compounds disclosed in published PCT Nos: WO 2010/000066, WO 2011/082487; WO 2011/082488; WO 2012/145330; WO 2012/139039; WO 2012/145328; WO 2013/028572; WO 2013/028791; WO 2014/179867; WO 2015/031984; WO 2016/058080; WO 2016/058082; WO 2016/112455; WO 2016/141458; WO 2017/177307; WO 2017/210771; WO 2018/045450; WO 2019/226991; WO 2020/081999, and WO 2020/198710, which are hereby incorporated by reference in their entireties.

Transcriptionally active androgen receptor plays a major role in CRPC in spite of reduced blood levels of androgen (Karantanos, T. et al Oncogene 2013, 32, 5501-5511; Harris, W. P. et al Nature Clinical Practice Urology, 2009, 6, 76-85). AR mechanisms of resistance to ADT include: overexpression of AR (Visakorpi, T. et al Nature Genetics 1995, 9, 401-406; Koivisto, P. et al Scandinavian Journal of Clinical and Laboratory Investigation Supplementum 1996, 226, 57-63); gain-of-function mutations in the AR LBD (Culig Z. et al Molecular Endocrinology 1993, 7, 1541-1550); intratumoral androgen synthesis (Cai, C. et al Cancer Research 2011, 71, 6503-6513); altered expression and function of AR coactivators (Ueda, T. et al The Journal of Biological Chemistry 2002, 277, 38087-38094; Xu J. et al Nature Reviews Cancer 2009, 9, 615-630); aberrant post-translational modifications of AR (Gioeli D. et al Molecular and Cellular Endocrinology 2012, 352, 70-78; van der Steen T. et al International Journal of Molecular Sciences 2013, 14, 14833-14859); and expression of AR splice variants (AR-Vs) which lack the ligand-binding domain (LBD) (Karantanos, T. et al Oncogene 2013, 32, 5501-5511; Andersen R. J. et al Cancer Cell 2010, 17, 535-546; Myung J. K. et al The Journal of Clinical Investigation 2013, 123, 2948-2960; Sun S. et al The Journal of Clinical Investigation 2010, 120, 2715-2730). Anti-androgens such as bicalutamide and enzalutamide target AR LBD, but have no effect on truncated constitutively active AR-Vs such as AR-V7 (Li Y. et al Cancer Research 2013, 73, 483-489). Expression of AR-V7 is associated with resistance to current hormone therapies (Li Y. et al Cancer Research 2013, 73, 483-489; Antonarakis E. S. et al The New England Journal of Medicine 2014, 371, 1028-1038).

DETAILED DESCRIPTION

All publications, patents and patent applications, including any drawings and appendices therein are incorporated by reference in their entirety for all purposes to the same extent as if each individual publication, patent or patent application, drawing, or appendix was specifically and individually indicated to be incorporated by reference in its entirety for all purposes.

Definitions

While the following terms are believed to be well understood by one of ordinary skill in the art, the following definitions are set forth to facilitate explanation of the presently disclosed subject matter.

Compound I is N-{4-[(4-{2-[3-chloro-4-(2-chloroethoxy)-5-cyanophenyl]propan-2-yl}phenoxy)methyl]pyrimidin-2-yl}methanesulfonamide having the structure shown below. Compound I is disclosed in WO 2020/081999, which is hereby incorporated by reference in its entirety. In one embodiment, Compound I is an androgen receptor N-terminal domain inhibitor.

Throughout the present specification, the terms “about” and/or “approximately” may be used in conjunction with numerical values and/or ranges. The term “about” is understood to mean those values near to a recited value. Furthermore, the phrases “less than about [a value]” or “greater than about [a value]” should be understood in view of the definition of the term “about” provided herein. The terms “about” and “approximately” may be used interchangeably.

Throughout the present specification, numerical ranges are provided for certain quantities. It is to be understood that these ranges comprise all subranges therein. Thus, the range “from 50 to 80” includes all possible ranges therein (e.g., 51-79, 52-78, 53-77, 54-76, 55-75, 60-70, etc.). Furthermore, all values within a given range may be an endpoint for the range encompassed thereby (e.g., the range 50-80 includes the ranges with endpoints such as 55-80, 50-75, etc.).

The term “a” or “an” refers to one or more of that entity; for example, “a androgen receptor modulator” refers to one or more androgen receptor modulators or at least one androgen receptor modulator. As such, the terms “a” (or “an”), “one or more” and “at least one” are used interchangeably herein. In addition, reference to “an inhibitor” by the indefinite article “a” or “an” does not exclude the possibility that more than one of the inhibitors is present, unless the context clearly requires that there is one and only one of the inhibitors.

As used herein, the verb “comprise” as is used in this description and in the claims and its conjugations are used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. The present invention may suitably “comprise”, “consist of”, or “consist essentially of”, the steps, elements, and/or reagents described in the claims.

It is further noted that the claims may be drafted to exclude any optional element. As such, this statement is intended to serve as antecedent basis for use of such exclusive terminology as “solely”, “only” and the like in connection with the recitation of claim elements, or the use of a “negative” limitation.

The term “pharmaceutically acceptable salts” includes both acid and base addition salts. Pharmaceutically acceptable salts include those obtained by reacting the active compound functioning as a base, with an inorganic or organic acid to form a salt, for example, salts of hydrochloric acid, sulfuric acid, phosphoric acid, methanesulfonic acid, camphorsulfonic acid, oxalic acid, maleic acid, succinic acid, citric acid, formic acid, hydrobromic acid, benzoic acid, tartaric acid, fumaric acid, salicylic acid, mandelic acid, carbonic acid, etc. Those skilled in the art will further recognize that acid addition salts may be prepared by reaction of the compounds with the appropriate inorganic or organic acid via any of a number of known methods.

As used herein, “solvate” means a complex formed by solvation (the combination of solvent molecules with molecules or ions of the active agent of the present invention), or an aggregate that consists of a solute ion or molecule (the active agent of the present invention) with one or more solvent molecules. In the present invention, the preferred solvate is hydrate. Examples of hydrate include, but are not limited to, hemihydrate, monohydrate, dihydrate, trihydrate, hexahydrate, etc. It should be understood by one of ordinary skill in the art that the pharmaceutically acceptable salt of the present compound may also exist in a solvate form (solvate salt). The solvate is typically formed via hydration which is either part of the preparation of the present compound or through natural absorption of moisture by the anhydrous compound of the present invention. Solvates including hydrates may be consisting in stoichiometric ratios, for example, with two, three, four salt molecules per solvate or per hydrate molecule. Another possibility, for example, that two salt molecules are stoichiometric related to three, five, seven solvent or hydrate molecules. Solvents used for crystallization, such as alcohols, especially methanol and ethanol; aldehydes; ketones, especially acetone; esters, e.g. ethyl acetate; may be embedded in the crystal grating. Preferred are pharmaceutically acceptable solvents.

The term “treating” means one or more of relieving, alleviating, delaying, reducing, improving, or managing at least one symptom of a condition in a subject. The term “treating” may also mean one or more of arresting, delaying the onset (i.e., the period prior to clinical manifestation of the condition) or reducing the risk of developing or worsening a condition.

An “effective amount” means the amount of a formulation according to the invention that, when administered to a patient for treating a state, disorder or condition is sufficient to effect such treatment. The “effective amount” will vary depending on the active ingredient, the state, disorder, or condition to be treated and its severity, and the age, weight, physical condition and responsiveness of the mammal to be treated.

The term “therapeutically effective” applied to dose or amount refers to that quantity of a compound or pharmaceutical formulation that is sufficient to result in a desired clinical benefit after administration to a patient in need thereof.

As used herein, a “subject” can be a human, non-human primate, mammal, rat, mouse, cow, horse, pig, sheep, goat, dog, cat and the like. The subject can be suspected of having or at risk for having a cancer, such as prostate cancer, breast cancer, ovarian cancer, salivary gland carcinoma, or endometrial cancer, or suspected of having or at risk for having acne, hirsutism, alopecia, benign prostatic hyperplasia, ovarian cysts, polycystic ovary disease, precocious puberty, spinal and bulbar muscular atrophy, or age-related macular degeneration. Diagnostic methods for various cancers, such as prostate cancer, breast cancer, ovarian cancer, bladder cancer, pancreatic cancer, hepatocellular cancer, salivary gland carcinoma, or endometrial cancer, and diagnostic methods for acne, hirsutism, alopecia, benign prostatic hyperplasia, ovarian cysts, polycystic ovary disease, precocious puberty, spinal and bulbar muscular atrophy, or age-related macular degeneration and the clinical delineation of cancer, such as prostate cancer, breast cancer, ovarian cancer, bladder cancer, pancreatic cancer, hepatocellular cancer, salivary gland carcinoma, or endometrial cancer, diagnoses and the clinical delineation of acne, hirsutism, alopecia, benign prostatic hyperplasia, ovarian cysts, polycystic ovary disease, precocious puberty, spinal and bulbar muscular atrophy, or age-related macular degeneration are known to those of ordinary skill in the art.

“Mammal” includes humans and both domestic animals such as laboratory animals (e.g., mice, rats, monkeys, dogs, etc.) and household pets (e.g., cats, dogs, swine, cattle, sheep, goats, horses, rabbits), and non-domestic animals such as wildlife and the like.

All weight percentages (i.e., “% by weight” and “wt. %” and w/w) referenced herein, unless otherwise indicated, are measured relative to the total weight of the pharmaceutical composition.

As used herein, “substantially” or “substantial” refers to the complete or nearly complete extent or degree of an action, characteristic, property, state, structure, item, or result. For example, an object that is “substantially” enclosed would mean that the object is either completely enclosed or nearly completely enclosed. The exact allowable degree of deviation from absolute completeness may in some cases depend on the specific context. However, generally speaking, the nearness of completion will be so as to have the same overall result as if absolute and total completion were obtained. The use of “substantially” is equally applicable when used in a negative connotation to refer to the complete or near complete lack of action, characteristic, property, state, structure, item, or result. For example, a composition that is “substantially free of” other active agents would either completely lack other active agents, or so nearly completely lack other active agents that the effect would be the same as if it completely lacked other active agents. In other words, a composition that is “substantially free of” an ingredient or element or another active agent may still contain such an item as long as there is no measurable effect thereof.

Polymorphism can be characterized as the ability of a compound to crystallize into different crystal forms, while maintaining the same chemical formula. A crystalline polymorph of a given drug substance is chemically identical to any other crystalline polymorph of that drug substance in containing the same atoms bonded to one another in the same way, but differs in its crystal forms, which can affect one or more physical properties, such as stability, solubility, melting point, bulk density, flow properties, bioavailability, etc.

As used herein, the term “solid dispersion” is a system in a solid state (as opposed to a liquid or gaseous state) comprising at least two components, wherein one component is dispersed more or less evenly throughout the other component or components (homogenous mix). Generally, a solid dispersion formulation of a therapeutically active agent(s) refers to a dispersion mixture of the therapeutically active agent(s) in an inert carrier. Inert carriers can be a crystalline carrier (such as sugars), a polymeric carrier (such as HPMCAS), or a mixture of surfactants and polymers. Typically, a solid dispersion of a therapeutically active agent increases the surface area of the therapeutically active agent and enhances drug solubility and/or dissolution rate.

In one embodiment, the present disclosure relates to a crystalline form of Compound I (not a salt). In one embodiment, the present disclosure relates to a crystalline form of Compound I, which is Form A.

In one embodiment, the crystalline forms are characterized by the interlattice plane intervals determined by an X-ray powder diffraction (XRPD) pattern. The spectrum of XRPD is typically represented by a diagram plotting the intensity of the peaks versus the location of the peaks, i.e., diffraction angle 2θ (two-theta) in degrees. The intensities are often given in parenthesis with the following abbreviations: very strong=vst; strong=st; medium=m; weak=w; and very weak=vw. The characteristic peaks of a given XRPD can be selected according to the peak locations and their relative intensity to conveniently distinguish this crystalline structure from others. The % intensity of the peaks relative to the most intense peak may be represented as I/Io.

Those skilled in the art recognize that the measurements of the XRPD peak locations and/or intensity for a given crystalline form of the same compound will vary within a margin of error. The values of degree 2θ allow appropriate error margins. Typically, the error margins are represented by “±”. For example, the degree 2θ of about 17.48±0.2″ denotes a range from about 17.46 to 17.50 degree 2θ. Depending on the sample preparation techniques, the calibration techniques applied to the instruments, human operational variation, and etc., those skilled in the art recognize that the appropriate error of margins for a XRPD can be about ±0.7; ±0.6; ±0.5; ±0.4; ±0.3; ±0.2; ±0.1; ±0.05; or less.

Additional details of the methods and equipment used for the XRPD analysis are described in the Examples section.

In one embodiment, the crystalline forms are characterized by Differential Scanning calorimetry (DSC). The DSC thermogram is typically expressed by a diagram plotting the normalized heat flow in units of Watts/gram (“W/g”) versus the measured sample temperature in degree Celsius. The DSC thermogram is usually evaluated for extrapolated onset and end (outset) temperatures, peak temperature, and heat of fusion. A peak characteristic value of a DSC thermogram is often used as the characteristic peak to distinguish this crystalline structure from others.

Those skilled in the art recognize that the measurements of the DSC thermogram for a given crystalline form of the same compound will vary within a margin of error. The values of a single peak characteristic value, expressed in degree Celsius, allow appropriate error margins. Typically, the error margins are represented by “±”. For example, the single peak characteristic value of about “17.48±0.2” denotes a range from about 17.46 to 17.50. Depending on the sample preparation techniques, the calibration techniques applied to the instruments, human operational variations, and etc., those skilled in the art recognize that the appropriate error of margins for a single peak characteristic value can be ±2.5; ±2.0; ±1.5; ±1.0; ±0.5; or less.

Additional details of the methods and equipment used for the DSC thermogram analysis are described in the Examples section.

In one embodiment, the crystalline forms are characterized by Dynamic Vapor Sorption (DVS). The DVS profile is typically expressed by a diagram plotting the sample relative humidity (RH) versus the change in mass (%). The DVS profile provides information on hygroscopicity of the crystalline form at different RH conditions.

Additional details of the methods and equipment used for DVS are described in the Examples section.

In certain embodiments, upon in vivo administration, a prodrug is chemically converted to the biologically, pharmaceutically or therapeutically more active form. In certain embodiments, prodrugs are useful because they are easier to administer than the corresponding active form. For example, in certain instances, a prodrug may be more bioavailable (e.g., through oral administration) than is the corresponding active form. In certain instances, a prodrug may have improved solubility compared to the corresponding active form. In certain embodiments, prodrugs are less water soluble than the corresponding active form. In certain instances, such prodrugs possess superior transmittal across cell membranes, where water solubility is detrimental to mobility. In certain embodiments, a prodrug is an ester. In certain such embodiments, the ester is metabolically hydrolyzed to carboxylic acid upon administration. In certain instances the carboxylic acid containing a solid form of Compound I is the corresponding active form. In certain embodiments, a prodrug comprises a short peptide (polyaminoacid) bound to an acid group. In certain of such embodiments, the peptide is cleaved upon administration to form the corresponding active form.

In certain embodiments, a prodrug is produced by modifying a pharmaceutically active compound such that the Compound I will be regenerated upon in vivo administration. The prodrug can be designed to alter the metabolic stability or the transport characteristics of a drug, to mask side effects or toxicity, to improve the flavor of a drug or to alter other characteristics or properties of a drug. By virtue of knowledge of pharmacodynamic processes and drug metabolism in vivo, those of skill in this art, once a pharmaceutically active compound is known, can design prodrugs of the compound (see, e.g., Nogrady (1985) Medicinal Chemistry A Biochemical Approach, Oxford University Press, New York, pages 388-392).

General Procedures—Analytical Methods

X-Ray Powder Diffraction (XRPD)

Figures labeled “Image by PatternMatch v3.0.4” were generated using unvalidated software. XRPD patterns were collected with a PANalytical X'Pert PRO MPD diffractometer or a PANalytical Empyrean diffractometer using an incident beam of Cu radiation produced using an Optix long, fine-focus source. An elliptically graded multilayer mirror was used to focus Cu Kα X-ray radiation through the specimen and onto the detector. Prior to the analysis, a silicon specimen (NIST SRM 640e) was analyzed to verify the observed position of the Si (111) peak is consistent with the NIST-certified position. A specimen of the sample was sandwiched between 3-μm-thick films and analyzed in transmission geometry. A beam-stop, short antiscatter extension, and antiscatter knife edge, were used to minimize the background generated by air. Soller slits for the incident and diffracted beams were used to minimize broadening from axial divergence. Diffraction patterns were collected using a scanning position-sensitive detector (X'Celerator) located 240 mm from the specimen and Data Collector software v. 5.5. The data acquisition parameters for each pattern are displayed above the image (X'Pert PRO MPD) or within the Data Viewer v. 1.8 image (Empyrean) of each pattern in the Data section of this report.

XRPD Indexing

The high-resolution XRPD patterns were indexed using proprietary SSCI software (Triads™, see U.S. Pat. No. 8,576,985) or X'Pert High Score Plus 2.2a (2.2.1) in this study. Indexing and structure refinement are computational studies. Agreement between the allowed peak positions, marked with red bars, and the observed peaks indicates a consistent unit cell determination. Successful indexing of the pattern indicates that the sample is composed primarily of a single crystalline phase. Space groups consistent with the assigned extinction symbol, unit cell parameters, and derived quantities are tabulated below each figure showing tentative indexing solution. To confirm the tentative indexing solution, the molecular packing motifs within the crystallographic unit cells must be determined. No attempts at molecular packing were performed.

Thermogravimetry (TGA) and TGA/DSC Combo Analysis

TGA and TGA/DSC Combo analyses were performed using a Mettler-Toledo TGA/DSC3+ analyzer. Temperature and enthalpy adjustments were performed using indium, tin, and zinc, and then verified with indium. The balance was verified with calcium oxalate. The sample was placed in an open aluminum pan. The pan was hermetically sealed, the lid pierced, then inserted into the TG furnace. A weighed aluminum pan configured as the sample pan was placed on the reference platform. The furnace was heated under nitrogen. The data acquisition parameters are displayed in the images in the Figure section or Data section of this report.

Temperature Modulated Differential Scanning calorimetry (TMDSC)

TMDSC was performed using Mettler-Toledo DSC3+ differential scanning calorimeter. TOPEM® overlays the isothermal or ramped temperature with a time series of random temperature pulses of different durations. A tau lag adjustment is performed with indium, tin, and zinc. The temperature and enthalpy are adjusted with octane, phenyl salicylate, indium, tin and zinc. The adjustment is then verified with octane, phenyl salicylate, indium, tin, and zinc. The sample was placed into a hermetically sealed aluminum DSC pan, and the weight was accurately recorded. The pan lid was pierced then inserted into the DSC cell. A weighed aluminum pan configured as the sample pan was placed on the reference side of the cell. The data was collected from −50° C. to 160° C. with a modulation amplitude of ±0.25° C. and a 15 to 30 second period with an underlying heating rate of 2° C./minute.

Single Crystal X-Ray Diffraction (SCXRD)

1. Preparation of the Single Crystal Sample: A solution of Compound I in acetone was prepared and filtered through a 0.2-μm nylon filter into a clean glass vial covered with perforated foil. The sample was allowed to evaporate slowly to dryness at ambient temperature. A single crystal was carefully removed from the vial wall for analysis.

2. Data Collection: A colorless plate having approximate dimensions of 0.28×0.12×0.04 mm3, was mounted on a polymer loop in random orientation. Preliminary examination and data collection were performed on a Rigaku SuperNova diffractometer, equipped with a copper anode microfocus sealed X-ray tube (Cu Kαλ=1.54184 Å) and a Dectris Pilatus3 R 200K hybrid pixel array detector. Cell constants and an orientation matrix for data collection were obtained from least-squares refinement using the setting angles of 6525 reflections in the range 4.7930°<θ<77.0370°. The space group was determined by the program CRYSALISPRO (CrysAlisPro 1.171.38.41r, Rigaku Oxford Diffraction, 2015) to be P2₁/c (international tables no. 14). The data were collected to a maximum diffraction angle (2θ) of 155.124° at room temperature.

3. Data Reduction: Frames were integrated with CRYSALISPRO. A total of 13457 reflections were collected, of which 5294 were unique. Lorentz and polarization corrections were applied to the data. The linear absorption coefficient is 3.352 mm⁻¹ for Cu Kα radiation. An empirical absorption correction using CRYSALISPRO was applied. Transmission coefficients ranged from 0.789 to 1.000. Intensities of equivalent reflections were averaged. The agreement factor for the averaging was 2.22% based on intensity.

4. Structure Solution and Refinement: The structure was solved by direct methods using SHELXT (see Sheldrick, G. M. Acta Cryst. 2015, A71, 3-8). The remaining atoms were located in succeeding difference Fourier syntheses. The structure was refined using SHELXL-2014 (see Sheldrick, G. M. Acta Cryst. 2008, A64, 112-122; Id.). Hydrogen atoms residing on nitrogen were refined independently. Hydrogen atoms residing on carbon were included in the refinement but restrained to ride on the atom to which they are bonded. The structure was refined in full-matrix least-squares by minimizing the function:

∑w(F_(o)² − F_(c)²)²

where the weight, w, is defined as 1/[σ²(F_(o) ²)+(0.1009 P)²+(0.9289 P)], where P=(F_(o) ²+2F_(c) ²)/3. Scattering factors were taken from the “International Tables for Crystallography” (International Tables for Crystallography, Vol. C, Kluwer Academic Publishers: Dordrecht, The Netherlands, 1992, Tables 4.2.6.8 and 6.1.1.4). Of the 5294 reflections used in the refinements, only the reflections with intensities larger than twice their uncertainty [I>2□(I)], 4317, were used in calculating the fit residual, R. The final cycle of refinement included 351 variable parameters, 15 restraints, and converged with respective unweighted and weighted agreement factors of:

R = ∑F_(o) − F_(c)/∑F_(o) = 0.0559 $R_{w} = {\sqrt{\left( {\sum{{w\left( {F_{o}^{2} - F_{c}^{2}} \right)}^{2}/{\sum{w\left( F_{o}^{2} \right)}^{2}}}} \right)} = 0.1711}$

The standard deviation of an observation of unit weight (goodness of fit) was 1.05. The highest peak in the final difference Fourier had an electron density of 0.674 e/Å³. The minimum negative peak had a value of −0.649 e/Å³.

5. Calculated X-ray Powder Diffraction (XRPD) Pattern: A calculated XRPD pattern was generated for Cu radiation using MERCURY (Macrae, C. F. Edgington, P. R. McCabe, P. Pidcock, E. Shields, G. P. Taylor, R. Towler M. and van de Streek, J. J. Appl. Cryst., 2006, 39, 453-457) and the atomic coordinates, space group, and unit cell parameters from the single crystal structure.

6. Atomic Displacement Ellipsoid and Packing Diagrams: The atomic displacement ellipsoid diagram was prepared using MERCURY. Atoms are represented by 50% probability anisotropic thermal ellipsoids.

Example 1 Synthesis and Characterization of Crystalline Form A of N-(4-((4-(2-(3-chloro-4-(2-chloroethoxy)-5-cyanophenyl)propan-2-yl)phenoxy)methyl)pyrimidin-2-yl)methanesulfonamideN-(4-((4-(2-(3-chloro-4-(2-chloroethoxy)-5-cyanophenyl)propan-2-yl)phenoxy)methyl)pyrimidin-2-yl)methanesulfonamide (Compound I)

Step 1: A mixture of 4-(chloromethyl)-2-methylsulfanyl-pyrimidine (1) (324 mg, 1.86 mmol), 3-chloro-2-(2-chloroethoxy)-5-(2-(4-hydroxyphenyl)propan-2-yl)benzonitrile (2) (0.5 g, 1.43 mmol) and K₂CO₃ (493 mg, 3.57 mmol) in MeCN (4 mL) was stirred at 80° C. for 5 hrs. LCMS and HPLC showed the reaction was completed and 81.4% of the desired product formed. The resulting mixture was quenched with sat.NH₄Cl (10 mL) and extracted with EtOAc (10 mL×3). The combined organic layers were washed with brine (10 mL), dried over Na₂SO₄, filtered and concentrated under reduced pressure. The residue was purified by MPLC to give 3-chloro-2-(2-chloroethoxy)-5-(2-(4-((2-(methylthio)pyrimidin-4-yl)methoxy)phenyl)propan-2-yl)benzonitrile (3) (0.54 g, yield: 77.4%) as colorless syrup. ¹H NMR (400 MHz, CDCl₃) δ=8.54 (d, J=4.8 Hz, 1H), 7.45 (d, J=2.4 Hz, 1H), 7.32 (d, J=2.4 Hz, 1H), 7.22 (d, J=5.2 Hz, 1H), 7.12 (d, J=8.8 Hz, 2H), 6.89 (d, J=8.8 Hz, 2H), 5.09 (s, 2H), 4.43 (t, J=6.4 Hz, 2H), 3.88 (t, J=6.4 Hz, 2H), 2.59 (s, 3H), 1.65 (s, 6H). after work up: HPLC (220 nm): 94.7%. LCMS (220 nm): 93.5%. Exact Mass: 487.1; found 488.0/490.0.

Step 2: To a suspension of 3-chloro-2-(2-chloroethoxy)-5-(2-(4-((2-(methylthio)pyrimidin-4-yl)methoxy)phenyl)propan-2-yl)benzonitrile (3) (1.07 g, 2.19 mmol) in THF (20 mmL) was added a suspension of Oxone (5.39 g, 8.76 mmol) in water (20 mL) at 20° C. The mixture was stirred at 20° C. for 16 hrs. LCMS and HPLC showed the reaction was completed and 93.0% of the desired product formed. The resulting mixture was quenched with sat.Na₂SO₃. The aqueous layer was extracted with EtOAc (30 mL×3). The combined organic layers were washed with brine (30 mL), dried over Na₂SO₄, filtered and concentrated under reduced pressure to give 3-chloro-2-(2-chloroethoxy)-5-(2-(4-((2-(methylsulfonyl)pyrimidin-4-yl) methoxy)phenyl)propan-2-yl)benzonitrile (4) (1.04 g, yield: 91.2%) as colorless syrup. ¹H NMR (400 MHz, CDCl₃) δ=8.94 (d, J=4.8 Hz, 1H), 7.85 (d, J=4.8 Hz, 1H), 7.45 (d, J=2.4 Hz, 1H), 7.31 (d, J=2.4 Hz, 1H), 7.15 (d, J=8.8 Hz, 2H), 6.91 (d, J=8.8 Hz, 2H), 5.30 (s, 2H), 4.43 (t, J=6.4 Hz, 2H), 3.88 (t, J=6.0 Hz, 2H), 3.40 (s, 3H), 1.66 (s, 6H). IPC detection: HPLC (220 nm): 92.956%. LCMS (220 nm): 93.0%. Exact Mass: 519.1; found 520.1/522.1.

Step 3: A suspension of 3-chloro-2-(2-chloroethoxy)-5-(2-(4-((2-(methylsulfonyl)pyrimidin-4-yl)methoxy) phenyl)propan-2-yl)benzonitrile (4) (30 mg, 0.058 mmol), methanesulfonamide (11 mg, 0.12 mmol) and K₂CO₃ (15.9 mg, 0.12 mmol) in MeCN (2 mL) was stirred at 85° C. for 5 hrs. LCMS showed the reaction was completed and 91.6% of the desired product formed. The resulting mixture was partitioned between EtOAc (2 mL) and aq.NH₄Cl (2 mL). The aqueous layer was extracted with EtOAc (2 mL×3). The combined organic layers were washed with brine (2 mL), dried over Na₂SO₄, filtered and concentrated under reduced pressure to give Compound I, Form A (40 mg) as yellow solid. ¹H NMR (400 MHz, CDCl₃) δ=8.77 (br s, 1H), 8.64 (d, J=4.8 Hz, 1H), 7.45 (d, J=2.4 Hz, 1H), 7.32 (d, J=2.4 Hz, 1H), 7.29 (d, J=5.2 Hz, 1H), 7.13 (d, J=8.8 Hz, 2H), 6.90 (d, J=8.8 Hz, 2H), 5.11 (s, 2H), 4.43 (t, J=6.0 Hz, 2H), 3.88 (t, J=6.0 Hz, 2H), 3.48 (s, 3H), 1.65 (s, 6H). IPC detection: LCMS (220 nm): 91.6% purity. Exact Mass: 534.1; found 535.1/537.2.

XRPD spectrum was obtained for Form A as shown in FIG. 1 and Tables 1A-1B. The sample likely contains small amount of NaCl. The sharp peaks at 27.3±0.2 and at 31.7±0.2 degrees two-theta is consistent with the presence of NaCl. Form A was determined successfully in this study, and the results indicate it is an anhydrous/unsolvated material.

TGA/DSC thermograms were also obtained for Form A as shown in FIG. 2. By TGA, a weight loss of 2.2 wt % was observed from 50-230° C., which is likely due to the loss of residual solvents in the sample. The dramatic change in the slope of the thermogram starting at about 284° C. (onset) is likely associated with the decomposition of the material. By DSC, an endotherm is observed at approximately 182° C. (onset), which could be due to the melting of the material.

DVS (dynamic vapor sorption) analysis was carried out on Form A (Table 2, FIG. 3). The DVS profile of Form A displayed a total of 5.474% weight gain during sorption from 5% to 95% RH, with the majority of the weight gain occurred above 55% RH (1.978 wt % gain from 55% to 85% RH and 3.106 wt % gain from 85% RH to 95% RH). During desorption from 95% RH to 5% RH, the sample displayed 5.472% weight loss, and some hysteresis was observed from 95% to 25% RH. The DVS data suggest that Form A exhibits low hygroscopicity within 5%-55% RH, limited hygroscopicity within 55%-85% RH, and significant hygroscopicity within 85%-95% RH.

Solids recovered after DVS analysis was consistent with Form A by XRPD analysis.

Example 2 Solubility Experiments and Polymorph Screening Experiments

The approximate solubility of Compound I in various organic solvents was determined by adding solvent aliquots to weighed samples Compound I. Weighed samples of Compound I were treated with aliquots of the test solvents or solvent mixtures at ambient temperature. Complete dissolution of the test material was determined by visual inspection. Solubility was estimated based on the total solvent volume used to provide complete dissolution. The actual solubility may be greater than the value calculated because of the use of solvent aliquots that were too large or due to a slow rate of dissolution. If complete dissolution was not achieved during the experiment, the solubility is expressed as “less than” (<). If complete dissolution was achieved by only one aliquot addition, the value is reported as “larger than” (>).

A summary of the approximate solubility of Compound I in various organic solvents is provided in Table 3.

(b) Based on observations during the screen on samples at much larger scales, the approximate solubility in p-dioxane is within 35-103 mg/mL. (c) Equilibrium solubility data acquired at 24 hours.

Various method of polymorph screening was conducted as described below.

The slurry-trituration experiments were conducted by stirring Compound I in specified organic solvents or solvent mixtures at various temperatures for 4-12 days. Sufficient amounts of solids of Compound I were added to selected solvents or solvent mixtures so that excess solids remained. The mixtures were then triturated with stir bars at designated temperatures for specified periods of time. Solids were isolated by centrifugation using Spin-X centrifuge tubes equipped with a 0.45 μm nylon filter. Solids were air dried before analysis.

A summary of experimental conditions and results is included in Table 4. Based on XRPD analysis, all slurry-trituration experiments generated solids that are consistent with Form A of Compound I.

To examine the propensity of Compound I to exist as hydrates, the slurry-trituration experiments were also conducted in selected aqueous mixtures with high water activities (A_(w)≥˜0.7). As shown in Table 5, all the water activity slurries generated Form A of Compound I.

(b) Water activity values are approximate and represent the water activity of the solvent system at 25° C. The activity coefficient calculations are based on modeling the interactions between functional groups present in the components. These calculated water activity values were not verified experimentally.

Polymorph screening was performed using various solvent-based approaches including evaporation, cooling, solvent/anti-solvent addition, and combinations of the techniques. For slow cooling (SC) and fast cooling (FS) experiments, saturated or concentrated solutions of Compound I were prepared in selected solvents at elevated temperatures and filtered through pre-warmed 0.2-μm nylon filters (unless specified in Table 6) into pre-warmed clean vials at the temperature. Solutions were then removed from the heating plate and left at ambient conditions (FC), or allowed to cool to ambient temperature on the heating plate with heat turned off (SC). If no handleable amount of solids appeared in vials, samples were moved to sub-ambient conditions. If not handleable amount of solids appeared after sub-ambient storage, the experiment was converted to an anti-solvent addition experiment.

For solvent/anti-solvent addition (SAS) experiments, Sub-ambient solutions from cooling attempts, or saturated/concentrated solutions of Compound I prepared in selected solvents were filtered through 0.2-μm nylon filters into specified antisolvent at ambient temperature. Samples were either isolated immediately for analysis, or stirred at specified conditions before isolation. Detailed cooling and anti-solvent addition experimental conditions, observations, and XRPD results are summarized in Table 6.

When using dioxane as the solvent during solvent/anti-solvent addition attempts, it was observed that the choice of an anti-solvent significantly impacts the experimental results. As detailed in Table 6, the addition of a dioxane solution into H₂O generated Form A, while the addition into heptane or hexanes yielded Material B or Material D, respectively. Insufficient amount of solids were observed when a dioxane solution was added into Et₂O. In all these attempts, the solvent ratio was kept constant at 1:3 (v/v) of dioxane/anti-solvent.

Evaporation studies were conducted. For fast evaporation (FE) and slow evaporation (SE), solutions of Compound I were prepared in selected solvents and filtered through 0.2-μm nylon filters into clean glass vials, and allowed to evaporate at ambient temperature from open vials (FE) or from vials covered with perforated aluminum foil (SE). Fast evaporation was assisted with a steady flow of N₂ gas where indicated. Detailed experimental conditions, observations, and XRPD results for evaporation studies are summarized in Table 7.

The majority of the experimental conditions for polymorph screening generated solids that are consistent with Form A.

Example 3 Observation of Materials B, C, and D in Polymorph Screening Experiments

As shown in Example 2, multiple solvent/anti-solvent attempts were performed in 1:3 (v/v) dioxane/heptane (Table 6), which consistently produced Compound I in a form labeled as Material B. See FIG. 4 for XRPD spectrum of Material B. Indexing attempts on XRPD pattern of Material B were not successful.

Material B was found to be unstable upon drying (Table 8), and therefore it was not further characterized. A mixture of Form A and Material C was obtained when Material B was dried at 65-66° C. under vacuum. See FIG. 4 for XRPD spectrum of Material C with Form A. When dried at ambient conditions on a filter paper, Material B converted to a disordered Material C. Based on experimental conditions to generate Material B and its drying studies, without being bound to any theory, Material B could be a solvated material which can convert to Material C upon drying.

In order to evaluate the relative stability between Form A and Material C, a competitive slurry was performed. About equal amounts (by mass) of Material C (mixture w/some Form A) and Form A were added to acetone so that solids persisted and were stirred at room temperature for 9 days. Solids were isolated by centrifugation using Spin-X centrifuge tubes equipped with a 0.45 μm nylon filter. Beige solids were observed. By XRPD, the post-slurry solids are consistent with a pure phase of Form A indicating Form A is more stable than Material C under the examined condition. Material C could be an anhydrous material.

Material D was observed in 1:3 (v/v) dioxane/hexanes by solvent/anti-solvent addition followed by ambient slurry for 1 day (Table 5). Based on visual observations, Material D and Material B appear to have some similarity in their XRPD patterns. See FIG. 4 for XRPD spectrum of Material D. Indexing attempts on XRPD pattern of Material D were not successful.

Further analyses, including ¹H NMR and TGA/DSC were performed on Material D. The ¹H NMR spectrum of Material D is consistent with the provided chemical structure of Compound I. Based on the NMR spectrum, Material D contains about 0.9 mol/mol of dioxane and trace amount of hexanes.

The TGA/DSC thermograms of Material D are shown in FIG. 5. By TGA, a step-like weight loss is observed with an onset at about 93° C., indicating Material D is a solvated material. The sample displays a weight loss of 13.6 wt % within 48-125° C., corresponding to ˜0.96 moles of dioxane, which is consistent with the NMR data. The DSC thermogram shows an endotherm at about 90° C. (onset), which is consistent with the TGA step-like weight loss and is likely due to desolvation of Material D. Upon further heating, a sharp endotherm is observed at 182° C. (onset), which could be due to melting of Form A. Material D likely converts to Form A upon desolvation.

The endotherm observed at 182° C. is likely due to Form A melting because Material D was observed to desolvate into Form A by XRPD when dried at 50-52° C./vacuum conditions for 3 days (FIG. 6). Based on characterization data and the drying result, without being bound to any theory, Material D is likely a solvated material of Compound I.

Example 4 Amorphous Form of Compound I

Variety of solvent-based techniques, including rotary evaporation and lyophilization, were carried out to screen for an amorphous form of Compound I. Experimental conditions, observations, and XRPD results are detailed in Table 9.

Rotary evaporation experiments were performed using DCM as a solvent. Dilute solutions of Compound I were prepared in DCM and filtered through 0.2-μm nylon filters into a clear round bottom flasks. The flasks were attached to a rotary evaporator and immersed in a water bath at specified temperatures and DCM was rapidly evaporated to dryness under vacuum. The samples underwent secondary drying under vacuum at room temperature in a vacuum oven before XRPD testing.

The sample generated from the first rotary evaporation experiment was secondary dried at ambient temperature under vacuum for 1 day and then analyzed by XRPD. By XRPD, the sample displays broad halos with crystalline peaks due to NaCl, indicating successful generation of an amorphous form of Compound I (“x-ray amorphous”). See FIG. 7, third spectrum from bottom.

Materials described as “x-ray amorphous” are typically characterized further by thermal analysis where the appearance of a glass transition (T_(g)) provides support for the non-crystalline nature of the material. Temperature modulated DSC was performed on the material to investigate the T_(g) (Table 10). As shown in FIG. 8, T_(g) was observed at approximately 61° C. as a step change in the reversing heat flow signal. On further heating, an exotherm likely due to crystallization was observed at about 91° C. (peak). The endotherm at about 178° C. (onset) could be, without bound to any theory, due to melting of the crystallized material, which could be Form A based on crystallization study (Table 11). The endotherm has a slightly lower temperature than the endotherm observed for Form A (182° C., FIG. 2), which could be due to the specimen containing an amorphous or disordered portion (i.e., not completely crystallized during the analysis).

Further analyses including ¹H NMR and TGA were also collected on this amorphous sample (Table 10). The ¹H NMR spectrum was consistent with the chemical structure of Compound I and contains trace amount of DCM. By TGA (FIG. 9), about 1.0 wt % loss is observed from 45-200° C., which is likely due to the residual DCM and moisture in the material. The dramatic change in the slope of the TGA thermogram starting at 280° C. (onset) is likely associated with the decomposition of the material. This amorphous form of Compound I was observed to become disordered Form A upon ambient storage in a desiccator for about 10 days (FIG. 10, top spectrum), indicating amorphous Compound I is physically not stable and crystallizes into Form A at ambient temperature. A repeated rotary evaporation attempt from DCM solution generated disordered Compound I Form A (FIG. 7, second spectrum from bottom) after the sample was secondary dried at ambient temperature under vacuum for 3 days, which provides further evidence that amorphous Compound I is not physically stable.

One lyophilization experiment targeting amorphous Compound I was performed from a diluted solution in dioxane. A dilute solution of Compound I in dioxane was prepared and flash frozen by filtering it through a 0.2-μm nylon filter into a clean glass flask in dropwise. The glass flask was pre-cooled to −78° C. in a dry ice/acetone bath. The sample was attached to a Labconco FreeZone 71040 BenchtopFreeze Dryer and lyophilized for 6 days.

The resulting solids were found to be disordered Compound I by XRPD (FIG. 7, bottom spectrum). Crystallization studies were performed on this disordered material (Table 10) and solids were stirred in acetone and H₂O for 4 days at ambient conditions. Both experiments generated crystalline Form A (FIG. 10, bottom two spectra).

Solubility: Generally, the solubility of an amorphous form is higher than that of the corresponding crystal form, due to the lack of crystalline lattice forces in the amorphous state. Solubility of the amorphous form of Compound I was studied by slow addition of the amorphous form from an organic stock solution into the pH 6.5 phosphate-buffered saline (PBS) solution or 0.5% wt simulated intestinal fluid (SIF) in pH 6.5 PBS. When the amorphous solubility is reached, a drug-rich phase forms which typically scatters light (e.g., liquid-liquid phase separation or LLPS), which can be detected by scattering of UV/Visible light and/or by dynamic light scattering (DLS).

No scattering event prior to crystallization was observed. Based on the data obtained, the amorphous solubility in pH 6.5 PBS and 0.5% SIF (pH 6.5) was >2.5 μg/mL and >25 μg/mL, respectively (FIG. 16). While an exact concentration could not be determined in this test, the amorphous solubility appears to be at least 20× higher than the crystalline solubility in simulated intestinal media. FIG. 16 shows concentration (solids lines) and scattering (dotted lines) vs. time during addition of a 95:5 THF:Water solution of amorphous form of Compound I into blank PBS or 0.5% SIF in PBS.

Example 5 Single Crystal Structure Determination for Form A of Compound I

During the screen, single crystals of Form A were observed by slow evaporation from an acetone solution (Table 7). A suitable single crystal was therefore selected and analyzed by single-crystal X-ray diffractometry, and the structure of Form A was determined successfully.

The crystal system is monoclinic and the space group is P2₁/c. The cell parameters and calculated volume are: a=17.5550 (2) Å, b=10.96169 (13) Å, c=13.7961 (2) Å, α=90°, β=104.5717 (15)°, γ=90°, and V=2569.40 (6) Å³. In one embodiment, single crystals of Form A has a density of about 1.384 g/cm³. The molecular weight is 535.43 g/mol with Z=4, resulting in a calculated density of 1.384 g/cm³. Standard uncertainty is written in crystallographic parenthesis notation, e.g. 0.123 (4) is equivalent to 0.123±0.004.

The quality of the structure obtained was high, as indicated by the fit residual, R, of 0.0559 (5.59%). R-factors in the range 2%-6% are quoted to be the most reliably determined structures (Glusker, Jenny Pickworth et al. Crystal Structure Analysis: A Primer, 2^(nd) ed.; Oxford University press: New York, 1985; p. 87). The asymmetric unit was determined to contain one Compound I molecule. The cyano and chlorine moieties on the phenyl ring were found to be rotationally disordered by 180°, refining to 78% in the predominant orientation. The calculated XRPD pattern of Form A from the single crystal data is shown in FIG. 11, along with the experimental pattern acquired (see Example 1).

Example 6 Activity of Exemplary Compounds in Cellular Assays

LNCaP cells were transiently transfected with the PSA (6.1 kb)-luciferase reporter for 24 h, and then treated with indicated concentration of representative compounds with synthetic androgen, R1881 (1 nM) for 24 h. After 24 h of incubation with R1881, the cells were harvested, and relative luciferase activities were determined. To determine the IC₅₀, treatments were normalized to the maximum activity with androgen-induction (in the absence of test compounds, vehicle only) (Table 12).

Luciferase Assay: Lysates were thawed on ice then collected into V-bottom 96-well tissue culture plates. Lysates were centrifuged at 4° C. for 5 minutes at 4000 rpm. To measure luminescence of LNCaP cell lysates the Firefly Luciferase Assay System (Promega) was employed, according to manufacturer's protocol.

Statistical analyses were performed using GraphPad Prism (Version 6.01 for Windows; La Jolla, Calif., USA). Comparisons between treatment and control groups were compared using Two-Way ANOVA with post-hoc Dunnett's and Tukey's tests. Differences were considered statistically significant at P values less than 0.05. Densitometric quantification of relative AR levels was determined by Image.

Reference Compound X and EPI-002 have the following structures:

Cell Proliferation Assay: Cell proliferation/viability was measured in LNCaP and PC3 cells with Alamar blue, and proliferation was measured in LN-CaP95 cells with BrdU incorporation. In LNCaP cells, AR specific proliferation is calculated by measuring the difference between control cells treated with or without 0.1 nM R1881. See Table 13.

Example 7 In Vivo Activity of Representative Compounds in LNCaP Xenografts Model

Tumor growth was measured in male NCG mice bearing LNCaP tumors. Castration was performed when tumors reached ˜100 mm³ and dosing (60 mg/kg PO qd) started 1 week after castration. Body weight of the mice were captured biweekly in the animals which showed no drug related toxicity. Individual tumor volume change from baseline measured at the end of the experiment. See FIG. 12. Data demonstrated that the representative compounds showed activity and induced partial regressions of tumor growth. The C_(min) at 5 mg/kg PO and extrapolated C_(min) in efficacy of the representative compounds are shown in Table 14.

Example 8 Solid Dispersion Composition Study 1

Compound I has very low crystalline solubility and very high amorphous solubility enhancement. It crystallizes rapidly from supersaturated aqueous solutions, dosed alone or with pre-dissolved precipitation-inhibiting polymers. Amorphous form of Compound I has a moderate glass transition temperature (Tg=62° C.) and partially re-crystallizes during heating of the amorphous form (Class 2 glass former).

Based on these characteristics, compositions were prepared at 10% active loading with 5 different polymers or polymer blends (Table 15). All manufactured formulations were amorphous by x-ray powder diffraction (XRPD).

Five spray dried dispersion (SDD) compositions were successfully manufactured with high yields on a Bend Lab Dryer with 35 kg/hr drying capacity (BLD-35). All SDDs were sprayed at the same atomization pressure (120 psig). After spray drying, the SDDs were secondary dried in a heating vacuum tray dryer for about 24 hours to remove residual solvent. Manufacturing parameters are listed in Table 16.

All SDDs contained amorphous form of Compound I by X-ray diffraction analysis (FIG. 13). The Tg of each SDD was dominated by the type of polymer as determined by modulated differential scanning calorimetry (mDSC). A water or solvent loss peak is observed for each SDD, being most intense for SDD composition D (FIG. 14). The solid lines of the mDSC thermograms of FIG. 14 are the reverse heat flow and the dashed lines are the non-reversing heat flow. Summary of the mDSC data is listed in Table 17.

SDD compositions G-M of Compound I were successfully manufactured with high yields on a Bend Lab Dryer with 35 kg/hr drying gas capacity (BLD-35) (Table 18). All SDDs were sprayed at the same atomization pressure (120 psig). After spray drying, the SDDs were secondary dried in a heating vacuum tray dryer at 40° C. for about 23 hours to remove residual solvent. Manufacturing parameters are listed in Table 19.

Secondary Drying was monitored by headspace gas chromatography in a separate tray drying space for an SDD composition of Table 18. Prior to secondary drying (wet sample), residual solvent in the SDD composition of Table 18 at storage temperature of 5° C. and 30° C. in sealed, stainless steel containers. Some solvent loss during storage and/or sampling was observed. SDD dried quickly during secondary drying, falling below ICH limits for residual DCM (600 ppm limit and permitted daily exposure of 6.0 mg/day) in less than 2 hours. Data supports secondary drying step of about 6 hours.

All manufactured formulations (stored at 2-8° C. after manufacturing) were amorphous by x-ray powder diffraction (XRPD), exhibiting the expected amorphous halo with no evidence of crystalline Compound I after manufacturing.

Tg of selected SDD compositions were determined by modulated differential scanning calorimetry (mDSC). The dry Tg (Tg determined under dry conditions) decreased with increased loading of Compound I. The dry Tg of all the SDD compositions showed sufficiently high for storage under dry conditions Table 20. The Tg decreased at elevated RH due to plasticization by absorbed water. SDD compositions I and K absorbed about 3% water at 75% RH while SDD composition M absorbed about 6% water, which is consistent with the decrease in Tg at 75% RH observed for SDD composition M.

After spray drying, the SDDs were secondary dried in a heating vacuum tray dryer at 40° C. with 3 liters per minute or 2.5 liters per minute of N₂ sweep gas for about 18.5-23 hours to remove residual solvent.
